This invention provides a high frequency sewing machine. The high frequency sewing machine comprises: a pair of belt loops (upper and lower) that press onto and transport a processed material from above and below, a pair of rollers (upper and lower) press onto the processed material from above and below, an upper electrode and a lower electrode that are oppositely placed and press onto the processed material from above and below, a high frequency power applicator, a controller, and an upper roller and an upper electrode that are opposite placed relative to a lower roller and a lower electrode, a roller elevator and an electrode elevator mechanism that raise and lower between an upper/farther position and a nearby position. Furthermore, a switching control changes the operation modes between a first bonding operation mode and a second bonding operation mode. The mode switching prevents pressed creases and burn marks, burnt fabric, and appearance deterioration due to wrinkles. Moreover, even curved portion can
